Are the IP's for the host and the jail on the same network? A look
at the relevant portions of rc.conf from both the host and the jail
would be most helpful in troubleshooting the problem.
You'll also want to make sure that sshd in the host is being told to
listen only to it's IP. If you don't and there's no sshd running in
the jail, you'll get a connection to the host instead of the jail.
